Compiler Crashes When Building Swift System

Table of Contents

Created by gh-md-toc

  • Swift Version: 5.3, 5.4-dev (Windows)
  • MacOS Version: 11.1, 10.15 (GitHub Actions)
  • Linux Version: Ubuntu 20.04, 18.04 (Docker)

Windows Swift version:

compnerd.org Swift version 5.4-dev (LLVM e2976fe639d1f50, Swift 769cfce6ed904e0)
Target: x86_64-unknown-windows-msvc

Mac Swift version:

Apple Swift version 5.3.2 (swiftlang-1200.0.45 clang-1200.0.32.28)
Target: x86_64-apple-darwin20.2.0

Reproduction Steps

Steps to reproduce:

  • Install Docker to test on Linux
  • Clone main branch of apple/swift-system
  • Run swift build on Mac and note that compilation succeeds
  • Run docker run -v $(pwd):/src -w /src -it swift:latest swift build to build on Linux and note that compilation fails

Compilation Output

Linux Compilation Output

Linux compilation output:

$ docker run -v $(pwd):/src -w /src -it swift:latest swift build
